SIGNAL.

SPECIFICATION forming part of Letters Patent No. 749,870, dated January 19, 1904.

Application filed August 2, 1902.

To all whom it may concern.-

. Be it known that I, J OHANNES J AOOBUS LUY- TEN, mechanician, a subject of the Queen of the Netherlands, residing at Batavia, Java, have invented certain new and useful Improvements Relating to Signals, of which the following is a specification;

. The signals by which the rail-track and station personnel of railways indicate to the engine-drivers the state of the line are often not visible in time or at allfor example, in mist or fog or when snowing. Auxiliary signals are therefore employed, which indicate to the locomotive-driver the position of the main signals at a certain distance in front of the latter. The auxiliary signals in use are placed by the side of the rail-track, as are the main signals, and the signaling is similarly given as by the main signalsthat is to say, in the auxiliary signals by difierent positions of a round disk and in the main signals by different positions of an arm by day and by difiernal, as in the known auxiliary signals, is connected with the main signal by a wire in such a manner that its position is changed simultaneously with that of thelatter and to an indicator provided in the locomotive cabin, which indicator on the passage of the auxiliary signal is displaced and indicates to the engine-driver the position of the main signal by day or night, as well as in good or bad weather, and always in the same manner and with the same certainty.

An auxiliary signal according to the present invention is illustrated in the drawings, in which Figure 1 illustrates the transmitter in elevation. Fig. 2 is a corresponding plan. Fig. 3 is an elevation of the indicator, and Fig. 4 is a plan thereof.

The transmitter consists of the double-armed lever b, pivotally mounted on a horizontal pin Serial No. 118,156. (No model.)

upon the pillar a, which lever has a pulley c and a disk 0? at one end and a counterweight e at the other. the foot and top of the pillar a and respectively carry pulleys h, z', and k, over which runs the wire rope Z. At one end of the latter hangs the weight on, while the opposite end is supposed to be connected with the main signal.

The indicator consists of a double-armed lever n, which is pivotally mounted upon a horizontal pin on the roof of the locomotive-cabin and is connected at one end withv the slide 0, provided in the front wall of the cabin, and at its other end with the piston 12. The latter is constantly pressed upwardly by the spiral spring 0', which is contained within the socket s, fixed upon the side wall of the cabin, so that the lever it ordinarily assumes the position shown in the drawings. The angular ledge t is fixedly connected upon the slide 0 and serves to uplift the indicating-slide c, which is guided in the guides '21,.

The indicatingslide 0 is provided with three apertures 1, 2, and 3, covered with differently-colored glass, of which apertures in the lowest position of the indicating-slide o the highest, 1, corresponds with an aperture 4 in the front wall of the engine-cabin.

Upon one arm of the lever 12 the rail 20 is fixedly connected, and thelatter runs under the pulley a when the locomotive passes the transmitter, whereby the lever 02. is displaced according to the position of the lever b. In the stop position of the main signal the weight m of the transmitter rests upon the disk d, so that the lever Z) assumes the position shown in the drawings. In this position the pulley c meets the rail '10 at the point x and presses it down against the action of the spring r to an extent corresponding to the distance between the points w and 2, whereby the indicatingslide 4: is uplifted so far as to bring its lowest aperture 3 in position to coincide with the aperture i and to color the light passing through the latter-for example, red.

In the all-clear position of the main signal the disk d is relieved of the weight 172, and the lever 5 under the action of the counterweight 6 takes such a position that the pul- Arms f and g are secured at ley c meets the rail an only at the point 3 and therefore presses it downward only to an extent corresponding to the distance between the points y and zc'. 6., to an extent equal to one-half the distance between the points 00 and z. The indicating-slide c is thereby moved only so far that its aperture 2 coincides with the aperture 4: and that the light passing through is, for example, colored green.

As soon as the pulley 0 releases the rail w the lever n by the spring 7' is brought back into its original position. The slide 0 and the angular ledge treturn, therefore, to their lowest position. The indicating-slide c,on the contrary, remains in its uplifted position by virtue of the friction of its lateral springs in the guides 14 until the engine-driver presses it down.

At night a lantern is placed before the aperture 4, the light of which passes through the aperture. in front of the driver and its operation is certain, being unaffected by bad weather or in any other way. By the slide 0 also a small meter may be actuated to indicate the distance traveled over.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In auxiliary signaling apparatus for railways in combination, a transmitter provided near the rail-track, an indicator fitted within the locomotive-cabin, said indicator consisting of a contact-lever directly operated by the transmitter, and means for indicating the condition of the line according to the extent of movement given to the contact-lever by the I auxiliary signal, substantially as described.

2. In auxiliary signaling apparatus for railways in combination, a transmitter provided near the rail-track and operated by the main signal, an indicator fitted within the locomo tive-cabin, said indicator consisting of a contact-lever directly operated by the transmitter, a slide positively connected to said contactlever, a loose indicating-slide moved by said slide, said loose indicating-slide having aperturescarrying diiferent-colored glass, and capable of being held in any position into which it is uplifted by the slide aforesaid, and an aperture in said cabin in the line of the apertures in the loose indicating-slide, substantially as described.
